Skincare compositions

Abstract

According to the present invention there is provided a multi-phase, fluid skincare composition comprising (a) at least one cream phase; and (b) at least one gel phase; wherein the cream phase and the gel phase are visually distinct phases that are packaged in physical contact; wherein the viscosity ratio of the cream phase to the gel phase is 1.25 or greater:1 or 1:1.25 or greater, preferably 1.25 or greater:1; wherein the viscosity of the cream phase is at least 15 Pa-s; wherein the viscosity of the gel phase is at least 10 Pa-s; wherein the cream phase and the gel phase are present in the composition at a level such that the weight ratio of cream phase to the gel phase is within the range of from 65:35 to 35:65; and wherein the viscosity is measured at 23° C. The present invention also provides a collapsible tube having an outlet bore and containing the composition as defined above, wherein the tube is filled such that, when the composition is extended from the outlet bore, the extruded composition comprises the cream phase and the gel phase that are visually distinct from one another and within a weight ratio of the cream phase to the gel phase of between 65:35 and 35:65 across the cross-section of the extrusion. The present invention also provides a use of the composition defined above for the purpose of one or more of moisturising the skin, including hydrating the skin, improving the radiance of the skin, improving skin suppleness, reducing skin tightness, nourishing skin and/or reducing dryness. The present invention also provides a use of the composition defined above for the purpose of topical application to any one or more of the face, the neck skin and/or the decollete, preferably the face.

The invention claimed is: 
     
       1. A multi-phase, fluid skincare composition comprising:
 (a) at least one cream phase; and 
 (b) at least one gel phase; 
 wherein the at least one cream phase and the at least one gel phase are visually distinct phases that are packaged in physical contact; 
 wherein a viscosity ratio of a viscosity of the at least one cream phase to a viscosity of the at least one gel phase is from 1:3 to 3:1; 
 wherein the viscosity of the at least one cream phase is between 45 Pa·s and 55 Pa·s; 
 wherein the viscosity of the at least one gel phase is between 23 Pa·s and 31 Pa·s; 
 wherein the at least one cream phase and the at least one gel phase are present in the composition at a level such that a weight ratio of the at least one cream phase to the at least one gel phase is within the range of from 52:48 to 48:52; 
 wherein the at least one cream phase is in the form of a water-in-oil and/or silicone emulsion; and 
 wherein the viscosity is measured at 23° C. using a Brookfield RVDV-I Prime viscometer with a heliopath, a speed of 10 revolutions per minute (rpm) for a time of 30 seconds using a T Bar spindle. 
 
     
     
       2. The composition of  claim 1 , wherein the composition comprises a bitter substance. 
     
     
       3. The composition of  claim 2 , wherein the bitter substance is chosen from denatonium compounds, aromatic oils,  eucalyptus  oil, bitter almond oil, menthol, or fruit aroma substances. 
     
     
       4. A collapsible tube having an outlet bore and containing the composition of  claim 1 , wherein the tube is filled such that, when the composition is extruded from the outlet bore, the extruded composition comprises the at least one cream phase and the at least one gel phase that are visually distinct from one another and within the weight ratio of the at least one cream phase to the at least one gel phase of between 52:48 and 48:52 across the cross-section of the extrusion. 
     
     
       5. The collapsible tube of  claim 4 , wherein the tube is filled such that, when the composition is extruded from the outlet, the composition forms at least one visually distinct pattern selected from the following patterns: striped, marbled, check, mottled, veined, speckled, ribbons, helical, grooved, ridged, waved, sinusoidal, spiral, contoured, weave or woven, and combinations thereof. 
     
     
       6. A method of moisturising skin, comprising topically applying the composition of  claim 1  to the skin. 
     
     
       7. The method of  claim 1  comprising topical application to any one or more of the face, the neck skin and/or the décolleté. 
     
     
       8. The composition of  claim 1 , wherein the at least one cream phase is in the form of a water-in-oil emulsion.
